Abstract: The system (200) has a processor (260) connected with an image sensor (250). A pointer (270) is reflected by a reflecting element (220) to form a mirror image when the pointer approaches a rectangular region of an input field (210), so that the pointer and the mirror image lie in a scanning region of the sensor. The sensor detects the pointer and the mirror image and the processor calculates a position of the pointer, when a part of the pointer adjoining at the region of the input field, a part of the mirror image adjoining at another region and the sensor run in a non collinear manner.

Abstract: PROBLEM TO BE SOLVED: To provide a variable size sensing system capable of adjusting and redefining the size of a sensing area. SOLUTION: A variable size sensing system includes: a first element; a second element; a third element; a fourth element; two image sensing devices; and a mark. The first element, the second element, the third element, and the fourth element are consecutively connected and thereby forming a frame. An inner edge of the frame defines a sensing area of a parallelogram shape. The size of the frame is changed by changing the length of the first element and the third element along a predetermined direction. A reflection material is formed on the surface of the second element, the third element, and the fourth element facing the sensing area. The two image sensing devices are installed at both ends of the first element, so that the two image sensing devices are always positioned in two corners of the sensing area and sense the whole area of the sensing area. The mark is installed on the surface of the third element facing the sensing area, and has a fixed distance from the fourth element. COPYRIGHT: (C)2010,JPO&INPIT
